resize terminal on initial loading of tickets creates traceback

[runborg]

Resizing the terminal (shrinking the windown in one directionwhen the initial loading of tickets screen is present creates a traceback when ticket loading is finished.

Traceback (most recent call last):
  File "/home/runarb/.local/bin/curitz", line 8, in <module>
    sys.exit(main())
  File "/home/runarb/.local/lib/python3.10/site-packages/curitz/cli.py", line 1182, in main

    self.box.addstr(
_curses.error: addwstr() returned ERR

i think the cause of this is that screen size is calculated before entering the initial load dialog and then used on the "window" thereafter. then as addwstr cant really paint the pixels thats removed fron the terminal at the edge of the window it crashes with a traceback.
